[对应知能达标训练P522] 说明：阅读理解每题2.5分，七选五每题2.5分，本试卷共42.5分。 Ⅰ.阅读理解 A (2025·重庆南开中学二模)Is it amazing to generate electricity by getting moisture(水汽)from the air surrounding you? Such devices，called MEG，have already been created with some regular items such as a piece of fabric.However，the researchers found it quite challenging to balance and maintain the moisture content between where it shouldn't be and where it is required to be. To fix this problem，the team led by Tan Swee Ching from National University of Singapore created a new MEG. One part of the fabric in their device is coated with a special gel(凝胶).This is what they called the wet region.The special water-absorbing gel is able to take in more than six times its original weight.This is the very thing used to harvest moisture coming from the air around.The other end of this device is the dry region，which doesn't have the gel.They specifically designed the fabric this way to make sure that the area stays dry and that the water is trapped only in the wet region. The wet and dry regions ensure water is maintained just in the wet area，even if this device is left in an open damp environment for a month.This demonstrates how effective the device is when it comes to maintaining its stable electrical output. The MEG device also has immediate potential applications，one of which is to make a portable power source.“With this unique structure，the electric performance of our MEG device is significantly improved in comparison with the previous ones，thus making it possible to power many common electronic devices，such as health monitors and wearable electronics，” Tan said. “The invention can be massively produced because it's easy for factories to get their hands on commercially available raw materials.When it is perfected，many people can finally get their hands on this small，yet powerful tool that they can easily and readily apply in the devices used for their daily use，” Tan added. [语篇解读]　本文是一篇说明文。文章聚焦于新加坡国立大学研发的新型水汽发电装置(MEG)，该装置通过创新的干湿区域设计解决了传统MEG的水汽平衡难题，兼具高效发电与易规模化生产的优势，为便携式电源领域带来突破性进展。 1．What is the main idea of paragraph 3? A．The structure of the device. B．The functions of the device. C．The operation of the device. D．The advantages of the device. 解析　段落大意题。根据第三段中“One part of...the wet region”和“The other end of...have the gel.”可推知，第三段主要讲述的是该装置的结构。故A项正确。 答案　A 2．What plays the major role in solving the problem of the previous MEG? A．The water-absorbing gel. B．The stable electrical output. C．The design of wet and dry regions. D．The specially-designed fabric. 解析　细节理解题。根据第一段中的“the researchers found it quite challenging to balance and maintain the moisture content between where it shouldn't be and where it is required to be.”可知，在旧装置中，研究人员很难在水汽不应该在的地方和它被要求在的地方之间平衡和保持水分；再结合第三段的描述可知，研究人员在设备中的织物的一部分上涂了一种特殊的凝胶，这就是所说的湿区域，而没有凝胶的另一端则被称为干区域，这种干湿区域的设计将水分仅保持在了湿区域，提高了该装置的效能。故干湿区域设计在解决以前的装置出现的问题中起了主要作用。故C项正确。 答案　C 3．Which statement will Tan probably agree with about the device? A．It has been widely applied. B．It has a promising future. C．It is a pioneering invention. D．It will succeed immediately. 解析　推理判断题。根据最后一段的描述可知，因工厂很容易得到原材料，所以该装置可以被大规模生产。该装置被完善后，很多人可最终使用这种小而强大的工具，将其容易且快捷地运用到日常使用的设备中，由此可推知，Tan很可能认为该装置的前景很好。故B项正确。 答案　B 4．Why did the author write this passage? A．To present a recent study on saving energy. B．To compare the new MEG with previous ones. C．To advocate a new way of generating electricity. D．To introduce a better device of producing power. 解析　写作目的题。Paras.1－2讲的是之前的水汽发电装置有一定缺陷，研究人员加以改良。Para.3主要介绍该设备的结构。Para.4主要介绍干湿区域设计的优点。Para.5主要介绍该装置的运用。Para.6主要介绍该装置的前景。由此可推知，作者写本文的目的是介绍一种更优良的发电装置。故D项正确。 答案　D B (2025·湖北五市调研)Surgeons often emphasize that in the event of a heart attack，time is crucial to saving heart muscle.The heart relies on a continuous supply of oxygen delivered by the heart's blood vessels (血管).When these vessels become blocked，the oxygen supply stops，and the heart's muscle cells begin to die within minutes.Survivors of heart attacks frequently suffer from permanent heart failure，with a worrying statistic showing that 50% of them may not survive beyond five years.“Eventually，their hearts become so weak that they can't sustain sufficient blood flow，and the ultimately stop，” explains Sanjay Sinha，a cardiologist at Addenbrooke's Hospital in Cambridge. However，within the next five years，there could be a new alternative—to grow live，beating “heart patches(补丁)”．Sinha，along with a team of biologists at the University of Cambridge's Stem Cell Institute，is working on this innovative approach.These heart patches are tiny，beating pieces of heart muscle.They are grown in lab dishes over a month.The process begins by taking blood cells and reprogramming them into a specific type of stem cell capable of developing into any cell type within the human body.Sinha is currently preparing to test these patches，first in mice and then in pigs.If successful，he hopes to set up a human trial within five years. In the United States，scientists from Stanford University are also working on creating heart patches.They envision a future procedure where ultrasound and MRI(超声波和磁共振) scans are used to identify damaged sections.Based on the shape of the section，a custom heart patch would be 3D printed to fit perfectly.Surgeons would then open the chest area and attach the patch directly to the heart. The major challenge with this method is establishing “electrical connectivity” between the new patch and the existing heart to ensure they beat in harmony.Additionally，the cost of developing and using these patches is significant，which could impact accessibility.However，if these challenges can be overcome，Sinha is optimistic that heart patches could transform the lives of millions worldwide. [语篇解读]　本文是一篇说明文。文章介绍了利用干细胞技术和3D打印开发“心脏补丁”的创新疗法，以应对心脏病发作导致的心肌损伤难题。 5．What is the function of paragraph 1? A．To reveal a finding. B．To offer a solution. C．To present a problem. D．To outline research. 解析　推理判断题。第一段主要讲述了心脏病发作时，时间对挽救心肌至关重要，血管堵塞会导致心肌细胞死亡，心脏病发作的幸存者常患有永久性心力衰竭，且一项令人担忧的统计数据显示50%的患者可能活不过五年。这些内容是在呈现心脏病发作后带来的严重问题，第二段中提到了技术的突破，故可推断出第一段的作用是呈现心脏病相关的严峻问题，为后文介绍“心脏补丁”解决方案做铺垫。 答案　C 6．What is the first step in growing heart patches? A．Launching a clinical trial in humans. B．Testing the heart patches on animals. C．Culturing heart patches in lab dishes. D．Generating stem cells from blood cells. 解析　细节理解题。根据第二段中的“The process begins by taking blood cells and reprogramming them into a specific type of stem cell capable of developing into any cell type within the human body.”可知，培育心脏补丁的第一步是从血细胞中生成干细胞。 答案　D 7．What is the purpose of using ultrasound and MRI scans? A．To create a 3D model of the heart. B．To locate damaged areas in the heart. C．To design the shape of the custom heart. D．To provide real-time guidance for operations. 解析　细节理解题。根据第三段中的“They envision a future procedure where ultrasound and MRI scans are used to identify damaged sections.”可知，使用超声波和磁共振扫描的目的是定位心脏受损部位。 答案　B 8．What is the major challenge in employing heart patches? A．Promoting global accessibility. B．Reducing production costs. C．Securing functional integration. D．Finding a suitable material. 解析　细节理解题。根据最后一段中的“The major challenge with this method is establishing ‘electrical connectivity’between the new patch and the existing heart to ensure they beat in harmony.”可知，使用心脏补丁的主要挑战是确保补丁与原有心脏的电信号同步，即功能整合。 答案　C C (2025·河北秦皇岛质检)Tennis is a popular sport with growing impact on trends，from clothing to movies.Now，it's even influencing furniture design.Belgian eco-designer Mathilde Wittock is creating furniture from discarded tennis balls.She chose to repurpose tennis balls due to their short lifespan.“It takes around 24 different manufacturing steps to produce a tennis ball，which is around five days.Then it has such a short lifespan，” Wittock told CNN.She aims to keep the 300 million tennis balls produced annually out of landfills. Wittock graduated in 2021 from Central Saint Martins with degrees in product design and natural design.Her degree project，Soundbounce，was a soundproof (隔音的) material made from recycled tennis balls，inspired by her sensitivity to noise.“Being very sensitive to noise，the tennis ball presented an opportunity to address this issue，” she said.“And，with noise pollution an ever-increasing problem，its effects are still largely unknown，but it is evident that it negatively impacts physical and mental health，so creating solutions for this is key.” Creating furniture from tennis balls is challenging.Wittock cuts each ball by hand along the white line，removes the brand logo，and creates frames with holes where the taken-apart balls fit.The result is a padded (有衬垫的) surface excellent for sound reduction.It takes her three to four weeks to complete a chair，which she sells for $2，900.Each ball is dyed by hand to match the client's space. The tennis balls Wittock uses are donated by tennis clubs.She now works with the Federation of Wallonia in Brussels，who offered her their entire stock of 100，000 balls.This will last for a while as Wittock can only use around 1，800 a week. The life of these tennis balls doesn't end as furniture.When the soft covering wears away or the rubber breaks down，the furniture pieces can be taken apart and recycled into other useful objects like playground mats.Being able to keep reusing materials is key to eco-design.Wittock's work demonstrates how discarded items can be transformed into functional，sustainable products. [语篇解读]　本文是一篇新闻报道。文章报道了比利时生态设计师Mathilde Wittock利用废弃网球制作家具的创意项目。 9．What was Soundbounce inspired by? A．Wittock's love for tennis. B．Wittock's design degrees. C．Wittock's sensitivity to noise. D．Wittock's wish to recycle balls. 解析　细节理解题。根据第二段中的“Her degree project，Soundbounce，was a soundproof material made from recycled tennis balls，inspired by her sensitivity to noise.”可知，Soundbounce的灵感来自她对噪声的敏感性。 答案　C 10．How does Wittock make the furniture sound-reducing? A．By using special machines. B．By creating padded surfaces. C．By adding extra coverings. D．By choosing thick materials. 解析　细节理解题。根据第三段中的“Wittock cuts each ball by hand along the white line...reduction.”可知，Wittock亲手沿着网球的白线将每个球切开，去掉品牌标识，然后制作出带有孔洞的框架，以便嵌入拆解后的网球。最终的成果是一个带有衬垫的表面，具有极佳的降噪效果。也就是说，Wittock通过创造有衬垫的表面使家具减少声音。 答案　B 11．Why does the author mention the Federation of Wallonia? A．To show Wittock's social skills. B．To show the large demand for balls. C．To show the support for Wittock's work. D．To show the popularity of Wittock's furniture. 解析　推理判断题。根据第四段中的“The tennis balls Wittock uses are donated by tennis clubs.She now works with the Federation of Wallonia in Brussels，who offered her their entire stock of 100，000 balls.”可知，Wittock使用的网球是来自网球俱乐部的捐赠，她现在与布鲁塞尔的瓦隆尼亚联合会合作，后者向她提供了他们全部的10万个球。故可推断出，作者提到瓦隆尼亚联合会是为了展示对Wittock工作的支持。 答案　C 12．What does the author think of Wittock's work? A．It's innovative. B．It's wasteful. C．It's ordinary. D．It's expensive. 解析　推理判断题。根据最后一段中的“Wittock's work demonstrates how discarded items can be transformed into functional，sustainable products.”可知，Wittock的作品展示了如何将废弃物品转化为实用的、可持续的产品。故可推断出作者认为Wittock的作品有创意。 答案　A Ⅱ.七选五 (2025·浙江Z20名校联盟第二次联考)In the freezing cold winter，air conditioners and heaters work overtime.The satisfaction of feeling a warm breeze against your skin is an amazing experience.__13__ What are to blame are often the inefficient home appliances you have.Luckily，there are smart home appliances that can alleviate this burden.These appliances offer many benefits，all while keeping your electric bill manageable. __14__ Smart lighting systems can detect activity in an area and adjust illumination accordingly，providing energy efficiency.In terms of security，smart door locks offer peace of mind by automatically securing your home when you leave.
